Haunt Controller: What about Box?

So the controller will consist of the Light Objects 12 Channel RF, the Freewire system, a computer power supply, a way to connect all the props to the controller (probably speaker terminals), perhaps a sound system and 110V to power it all. I want to be able to expand on it in the future. Where do I put it all? I want it to be hidden, a part of the display.



I can build this as a cabinet with doors, everything will then be protected from the elements.
